| Research Abstract |
This study is consist of two kinds of categories as shown below.
1.Development of automated opening/closing system for WYSIWYG-Net: Automated opening/closing system to achieve the multi-layer sampling for plankton and micro-nekton was developed. This system could be worked without an armored cable winch system and allows to conduct multi-layer sampling on any research vessel.
2.Utilization of LOPC (Laser Optical Plankton Counter) with net : The platform unit was made for zooplankton sampling with LOPC and the data from the net and LOPC were compared. From these results, the methods to estimate the density and to make a species distinction for zooplankton (krill, copepoda, etc.) were developed.
